| 21 | Paving block formed of rubber crumb and a method of manufacturing the same | US13621778 | 2012-09-17 | US09079347B2 | 2015-07-14 | Clark Chow |
| A hollow paving block comprises a substantially planar member having a first surface and a second surface opposite the first surface. The first surface of the planar member is a textured surface which functions as a top of the paving block. A side wall extends along and away from a periphery of the second surface of the planar member to define a cavity in the paving block. The side wall has a bevelled edge which extends about a mouth of the cavity. At least one protrusion extends along the second surface of the planar member. The paving block is formed in part from crumb rubber and polyolefin. | ||||||

| A method of making a rubber-containing polyolefin separator entails preparing a pre-mixture (18) that includes polyolefin material (1), silica (2), and processing oil (5) and delivering the pre-mixture to a multi-zone extruder (12) having a sheet die (34). The pre-mixture becomes partly gelled as it advances in the extruder. Rubber powder (6) added at a medial zone (Z4) of the extruder combines with the pre-mixture advancing in the extruder to form a gelled rubber-containing extrudate as it exits the sheet die. The extrudate is processed by extracting a portion of the processing oil to form a separator sheet with dispersed rubber powder in the form of domains of larger average size. The larger rubber domains exhibit a smaller average ratio of surface area to volume and thereby results in slower release by diffusion of the beneficial substance from the rubber domains to the battery electrolyte. | ||||||

| PURPOSE: A block mat of a composite elastic layer for the bottom of a playground and a manufacturing method thereof are provided to prevent sand from being permeated through the bottom of a playground by forming air holes between middle and lower layers. CONSTITUTION: A block mat of a composite elastic layer for the bottom of a playground comprises an upper layer, a middle layer, and a lower layer. The middle layer is manufactured in order to form air holes between multiple pore columns. The lower layer is manufactured in order to form multiple protrusions on one surface of the lower layer which is closed to the middle layer. The protrusions are engaged with parts of the air holes. | ||||||

| The present invention relates to a method for preparing a block mat with a composite elastic layer for the bottom of a playground, and a block mat with a composite elastic layer for the bottom of a playground prepared by the method, and more specifically, to a method for preparing a block mat with a composite elastic layer for the bottom of a playground, and a block mat with a composite elastic layer for the bottom of a playground prepared thereby, wherein the block mat comprises an upper layer, a middle layer and a lower layer to increase elasticity and bonding force, and the block mat is constructed in such a way that the elastic pillars of the middle layer are engaged with the protrusions of the lower layer. A block mat with a composite elastic layer for the bottom of a playground prepared by the method of the present invention comprises an upper layer, a middle layer having pores, and a lower layer, thereby preventing sand from penetrating the pores of the block mat, and can thus maintain excellent elasticity. | ||||||
